DPMS AR-10 Magazine Catch Assembly

A magazine catch assembly for AR-10 pattern rifles from DPMS. It is sold as an assembly rather than as a handful of loose small parts, which turns a worn or damaged catch into a bench job instead of a scavenger hunt through parts bins.

Large frame AR magazines carry more weight than AR-15 mags, and the catch takes that load every time a full magazine seats. Wear shows up as a magazine that drags going in, sits low, or refuses to lock at all. A punch and a few minutes puts a fresh one in. Worth keeping in the spares box for any large frame build that sees real round counts.
